Question

draw the graph of y= x square -2x -3 and find zeros. what do you notice​

Answer 1

Answer:

The graphs of y=x

The graphs of y=x 2

The graphs of y=x 2 and y=x+2 intersect at the x-coordinates of −1 and 2. Hence the roots of the quadratic equation x

The graphs of y=x 2 and y=x+2 intersect at the x-coordinates of −1 and 2. Hence the roots of the quadratic equation x 2

The graphs of y=x 2 and y=x+2 intersect at the x-coordinates of −1 and 2. Hence the roots of the quadratic equation x 2 −x−2=0 are {−1,2}
